o OK FOR MANUAL TRANSAXLE
CAUTION:A car with an automatic transaxle should
never be towed from the rear with the front
wheels on the ground. This can cause seri-
ous damage to the transaxle. If the car must
be towed from the rear, a towing dolly must
be used under the front wheels.
If the car is being towed with the rear wheels on
the ground, be sure the parking brake is re-
leased. o OK FOR AUTOMATIC OR MANUAL

D080D02A-AATEmergency Towing
For emergency towing when no commercial
tow vehicle is available, attach a tow cable,
chain or strap to one of the tie-down hooks
under the front of your car. Do not attempt to
tow your vehicle in this manner on any unpaved
surface. This could result in serious damage to
your car.
Nor should towing be attempted if the wheels,
drive train, axles, steering or brakes are dam-
aged. Before towing, be sure the transaxle is in
neutral and the key is in "ACC" (with the engine
off) or in the "ON" position (with the engine
running). A driver must be in the towed car to
steer it and operate the brakes.
NOTE:Before towing, check the level of the tran-
saxle fluid. If it is below the "HOT" mark on
the dipstick, add fluid. If you cannot add
fluid, a towing dolly must be used as de-
scribed above.

VEHICLE MAINTENANCE REQUIREMENTS
5-1
F010C01A-AATSpecified Scheduled Procedures
These are the procedures such as inspections,
adjustments and replacements that are listed in
the maintenance charts starting on page 5-3.
These procedures must be performed at the
intervals shown in the maintenance schedule to
assure that your warranty remains in effect.
Although it is strongly recommended that they
be performed by the trained technicians at your
Hyundai dealer, these procedures may be per-
formed at any qualified service facility.
It is suggested that genuine Hyundai service
parts be used for any required repairs or re-
placements. Other parts of equivalent quality
such as engine oil, engine coolant, manual or
auto transaxle oil, brake fluid and so on which
are not supplied by Hyundai Motor Company or
its distributor may be used without affecting
your warranty coverage but you should always
be sure these are equivalent to the quality of the
original Hyundai parts. Your Owner's Hand-
book provides further information about your
warranty coverage.

F010A01A-AATMAINTENANCE INTERVALS
Service Requirements
To ensure that you receive the greatest number
of miles of satisfying operation from your
Hyundai, certain maintenance procedures must
be performed. Although careful design and en-
gineering have reduced these to a minimum,
those that are required are of the utmost impor-
tance.
It is your responsibility to have these mainte-
nance procedures performed to comply with the
terms of the warranties covering your new
Hyundai. The Owner's Handbook supplied with
your new vehicle provides further information
about these warranties.
F010B01A-AATMaintenance Requirements
The maintenance required for your Hyundai can
be divided into three main areas:
o Specified scheduled procedures
o General checks
o Do-it-yourself maintenance
F010F01A-AAT
A Few Tips
o Whenever you have your Hyundai serviced,
keep copies of the service records in your
glovebox. This will help ensure that you can
document that the required procedures have
been performed to keep your warranties in
effect. This is especially important when
service is not performed by an authorized
Hyundai dealer.
o If you choose to do your own maintenance
and repairs, you may find it helpful to have
an official Hyundai Shop Manual. A copy of
this publication may be purchased at your
Hyundai dealer's parts department.

G030C01A-AATTo Check the Oil LevelG030D01A-AATAdding Oil
Before checking the oil, warm up the engine to
the normal operating temperature and be sure
your car is parked on level ground. Turn the
engine off.
Wait a minute, then remove the dipstick, wipe it
off, fully reinsert the dipstick and withdraw it
again. Then note the highest level the oil has
reached on the dipstick. It should be between
the upper ("FULL") and lower ("LOW") range.If the oil level is close to or below the "LOW"
mark, add oil until it reaches the "FULL" mark.
To add oil:
1. Remove the oil filler cap by turning it counter-
clockwise.
2. Add oil, then check the level again. Do not
overfill.
3. Replace the cap by turning it clockwise.
The distance between the "FULL" and "LOW"
marks is equal to about 1 quart of oil.
G040A02GK-AATCHANGING THE OIL AND FILTER
The engine oil and filter should be changed at
those intervals specified in the maintenance
schedule in Section 5. If the car is being driven
in severe conditions, more frequent oil and filter
changes are required.
The procedure for changing the oil and filter is
as follows:
1. Park the car on level ground and set the
parking brake. Start the engine and let it
warm up until the needle on the coolant
temperature gauge moves above the lowest
mark. Turn the engine off and place the gear
selector lever in "P" (automatic) or reverse
gear (manual transaxle). Set the parking
brake.
2. Open the hood and remove the engine oil
filler cap.

drain plug by turning it counterclockwise
with a wrench of the proper size. Be sure
that a drain pan is in position to catch the oil
as it drains out, then remove the drain plug.
WARNING:Be very careful when draining the engine oil
as it may be hot enough to burn you!
4. When the oil has stopped draining, replace
the drain plug using a new washer and
retighten by turning it clockwise.
Tightening torque is:
4.5 ~ 4.0 kgf.m (2.0L)
4.5 ~ 3.5 kgf.m (2.7L)
5. Remove the oil filter by turning it counter-
clockwise with a oil filter wrench of the
proper size. A certain amount of oil will
come out when you remove the filter. So be
sure to have your drain pan in place under-
neath it.
6. Install a new oil filter in accordance with the
instructions on the carton or on the filter
itself. Do not over-tighten. (Tightening
torque : 1.2 ~ 1.6 kgf.m)
Be sure that the mounting surface on the
engine is clean and that the old gasket is
removed completely. Lubricate the new gas-
ket on the filter with clean engine oil before
installation.
7. Refill the crankcase with the recommended
engine oil. Refer to the specification in chap-
ter 9 for engine oil capacity.8. Start the engine and check to be sure no oil
is leaking from the drain plug or oil filter.
9. Shut off the engine and recheck the oil level.
NOTE:Always dispose of used engine oil in an
environmentally acceptable manner. It is sug-
gested that it be placed in a sealed container
and taken to a service station for reclama-
tion. Do not pour the oil on the ground or
put it into the household trash.
WARNING:Used motor oil may cause irritation or can-
cer of the skin if left in contact with the skin
for prolonged periods of time. Wash your
hands thoroughly with soap and warm wa-
ter as soon as possible after handling used
oil.
G050A01A-AATCHECKING AND CHANGING THE EN-
GINE COOLANT
WARNING:
Do not remove the radiator cap when the
engine is hot. When the engine is hot, the
engine coolant is under pressure and may
erupt through the opening if the cap is
removed. You could be seriously burned if
you do not observe this precaution. Do not
remove the radiator cap until the radiator is
cool to the touch.
G050B01A-AATRecommended Engine Coolant
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant should
be compatible with aluminum engine parts.
Additional corrosion inhibitors or additives should
not be used. The cooling system must be main-
tained with the correct concentration and type
of engine coolant to prevent freezing and corro-
sion. Never allow the concentration of anti-
freeze to exceed the 60% level or go below the
35% level, or damage to the cooling system
may result. For proper concentration when add-
ing or replacing the engine coolant, refer to the
following table.

To Check the Coolant Level
The coolant level can be seen on the side of the
plastic coolant reservoir. The level of the cool-
ant should be between the "LOW" and "FULL"
lines on the reservoir when the engine is cold.
If the level is below the "LOW" mark, add
engine coolant to bring it up between "LOW"
and "FULL". If the level is low, inspect for
coolant leaks and recheck the fluid level fre-
quently. If the level drops again, visit your
Hyundai dealer for an inspection and diagnosis
of the reason.
G050D02A-AATTo Change the Engine Coolant
The engine coolant should be changed at those
intervals specified in the vehicle maintenance
schedule in Section 5.
CAUTION:Engine coolant can damage the finish of
your car. If you spill engine coolant on the
car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the park-
ing brake and remove the radiator cap when
cool.
2. Be sure your drain receptacle is in place.
Open the drain cock on the radiator. Allow
all the engine coolant to drain from the
cooling system, then securely close the drain
cock.
3. Check Section 9 for the capacity of the
cooling system in your car. Then, following
the manufacturer’s directions on the engine
coolant container, add the appropriate quan-
tity of coolant to the radiator.
4. Turn the radiator cap counterclockwise with-
out pressing down on it, until it stops. This
relieves any pressure remaining in the cool-
ing system. And remove the radiator cap by
pushing down and turning counterclockwise.
Now fill the radiator with clean demineral-
ized or distilled water. Continue to add clean
demineralized or distilled water in small quan-
tities until the fluid level stays up in the
radiator neck.5. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking.
WARNING:The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper-
ate even when the engine is not running.
Use extreme caution when working near the
blades of the coolant fan so that you are not
injured by a rotating fan blade. As the en-
gine coolant temperature decreases, the fan
will automatically shut off. This is a normal
condition.
